Today our salutes goes out to the LIGO team: On September 14, 2015 at 09:50:45 UTC the two detectors of the Laser Interferometer Gravitational Wave Observatory simultaneously observed a transient gravitational-wave signal. The signal sweeps upwards in frequency from 35 to 250 Hz... Read more...

Albert Einstein predicted the existence of Gravitational Waves in 1916 but he also thought that we would never be able to detect these tiny distortions in spacetime. Nevertheless gravitational-wave observatories have been built and constantly improved since the 1960's. LIGO operates two of these detectors. Put in their own words LIGO are listening for Gravitational Waves with Ears Wide Open. From 2002-2010 it was without succes. But after a major upgrade, with enhancements of the laser power and other parts of the hardware, operation was restarted in september 2015, and yesterday LIGO announced the first detection of gravitational waves ever and thereby proving Einsteins prediction correct.
